A Hydraulic Blanking Plug Kit is a set of threaded plugs and/or related closure components designed to close compatible ports or openings in hydraulic systems. Depending on the kit configuration, it may be used during equipment assembly, maintenance, storage, or transportation to help prevent fluid leakage where applicable and protect exposed connections from dust and other contaminants.

We support standard product selection and customized requirements, including non-standard threads, special dimensions, material selection, surface treatment, and logo marking. This gives OEMs, importers, and distributors greater flexibility when sourcing components for different applications.

Surface Treatment Options

Zinc Plating: Available in blue-white or yellow finishes for carbon steel components, providing corrosion protection under suitable service conditions.

Blackening: Provides a black surface finish for applications where appearance and basic surface protection are required.

Dacromet Coating: Available for specified applications requiring enhanced corrosion protection, subject to process availability and technical requirements.

Custom Finishes: Other surface treatments can be evaluated based on customer drawings and specifications.

Sealing & Connection Compatibility

Hydraulic blanking plugs must match the specified port geometry and operating conditions to ensure proper fit and closure.

- Thread Compatibility: Thread type, nominal size, pitch, and tolerance must match the target port specification.

- Sealing Interface: Sealing performance depends on the plug design and specified interface, such as a sealing face or O-ring feature where applicable.

- Operating Conditions: Pressure rating, hydraulic fluid compatibility, and operating temperature must be verified against the requirements of the specific component and application.
